SELF-CLEANING SPRAY VALVE ASSEMBLY |
摘要 |
Systems and methods for producing consistent spray patterns and for diminishing clogging experienced when applying spray adhesive from a spray gun are provided. One system includes an automatic non-atomizing spray valve operably coupled to a first and second flow valve. The spray and flow valves are electronically controlled using logic running on a processing unit. The logic is programmed to carry out a spray cycle that involves dispensing a first liquid from the spray valve (first phase) and then dispensing a second liquid through the same spray valve (second phase). Because the first liquid (e.g., water-based adhesive) has the potential to clog a nozzle of the spray valve, a short burst of the second liquid (e.g., cleaning fluid) is introduced to prevent the nozzle from clogging. The spray valve is configured as a pulse width modulated spray gun to further reduce clogging and to generate an evenly distributed spray pattern. |
